Training my wife for you Bulls

I have been training my young wife of 23 to be a slut for Bbc.
We started off filming us online and making her profile really slutty and watching all the black guys comment really turns her on,
We also now have bought a few big black dildos she fucks as she sucks my cock .
We often have fantasy of gangbangs and her biggest turn on is being raped by lots of big black dicks.
How should I proceed ?
Can you guys help with the next step of getting her fucking real black cocks
